Said reaction products contain free carboxyl groups and optionally ammonia or an organic base is added so that a sample of the reaction mixtureafter adding some water to enable a pH-readinghas a pH-value of 7.5 to 12.

The stable preparations are useful to finishing textile materials, especially to rendering wool non-felting.

The subject of the invention is a process for the manufacture of stable preparations of reaction products of epoxides, fatty amines and dicarboxylic acids, characterized in that at least (a) one epoxide which per molecule contains at least two epoxide groups, (b) one highermolecular fatty amine with 12 to 24 carbon atoms and (0) one aliphatic, saturated dicarboxylic acid with at least 7 carbon atoms, and optionally (0) one anhydride of an aromatic dicarboxylic acid with at least 8 carbon atoms or of an aliphatic dicarboxylic or monocarboxylic acid with at least 4 carbon atoms, and optionally one or more of the following components: (d) A resinforming aminoplast precondensate containing alkyl-ether groups, (e) an aliphatic diol with 2 to 22 carbon atoms and (f) a polyfunctional, preferably difunctional, organic compound which possesses, as functional groups or atoms, mobile halogen, vinyl or ester groups or at most one acid, nitrile, hydroxyl or epoxide group together with at least one other functional group or one atom of the 6 indicated type, are reacted with one another, in the presence of an organic solvent, to give a reaction product containing free carboxyl groups and are thereafter optionally treated, optionally at elevated temperature, with (g) ammonia or a water-soluble organic base, especially aliphatic tertiary monoamines or polyamines, and that provision is made, if necessary by adding further ammom'a or further water-soluble organic bases, that a sample of the reaction mixture contained in the organic medium shall, after dilution with water, have a pH value of 7 .5 to 12.

The epoxides (a) from which the component (a) is 3,769,365 Patented Oct. 30, 1973 obtained are preferably derived from polyhydric phenols or polyphenols, such as resorcinol, or phenol-formaldehyde condensation products of the type of the resols or novolaks. Bisphenols, such as bis-(4-hydroxyphenyl)- methane and above all 2,2-bis-(4-hydroxyphenyl)-propane, are especially preferred as starting compounds for the manufacture of the epoxides.

Compounds to be mentioned especially here are epoxides of 2,2-bis-(4'-hydroxyphenyl)-propane which have an 'epoxide content of 1.8 to 5.8 epoxy group equivalents/ kg., but preferably at least 5 epoxy group equivalents/ kg., and which correspond to the formula wherein 2 denotes a mean number having a value of 0 to 0.65. Such epoxides are obtained by reaction of epichlorohydrin with 2,2-bis-(4'-hydroxyphenyl)-propane.

Mono-fatty amines with 12 to 24 carbon atoms have above all proved to be very suitable components (b). As a rule, these are amines of the formula wherein x represents an integer having a value of 11 to 23, preferably 17 to 21. The amines are thus, for example, laurylamine, palitylamine, stearylamine, archidylamine or behenylamine. Mixtures of such amines, such as are obtainable as technical products, can also be used.

Alkylenedicarboxylic acids with 7 to 14 carbon atoms have above all proved advantageous components (0). As a rule, these are dicarboxylic acids of the formula 3 HOOC-(CHz)yCOOH wherein y denotes an integer having a value of 5 to 12, preferably 6 to 10.

Accordingly, possible components (c) are, for example, dicarboxylic acids, such as pimelic, suberic, azelaic or sebacic acid, nonanedicarboxylic acid, decanedicarboxylic acid, undecanedicarboxylic acid or dodecanedicarboxylic acid.

The components (c) can be employed alone or together with the component (c'). As the component (c), an anhydride of a monocyclic or bicyclic aromatic dicarboxylic acid with 8 to 12 carbon atoms or of an aliphatic dicarboxylic acid with 4 to 10 carbon atoms is preferentially used. Anhydrides of a monocyclic aromatic dicarboxylic acid with 8 to 10 carbon atoms have proved particularly advantageous. Optionally methyl-substituted phthalic anhydride is of particular interest.

Possible components (c') are, accordingly, anhydrides finch as, for example, maleic anhydride or phthalic anhyride.

Where the component (d) is used conjointly for the manufacture of the reaction products, its proportion, relative to the total of the components (a), (b), (c) and (d), is 10 to 50, especially 20 to 25, percent by weight.

The aminoplast condensates used as component (d) are completely etherified, or especially partially etherified, methylol compounds of nitrogen-containing aminoplastforming agents, such as urea, urea derivatives, for ex ample ethyleneurea, propyleneurea or glyoxalmonourein.

Preferably, however, etherified methylolaminotriazines are employed, such as, for example, alkyl ethers of highly methylolated melamine, of which the alkyl radicals contain 1 to 4 carbon atoms. Possible alkyl radicals are, amongst others, methyl, ethyl, n-propyl, isopropyl, nbutyl and n-hexyl radicals. In addition to such alkyl radicals, yet further radicals, for example polyglycol radicals, can also be present in the molecule. Furthermore, n-

contain 2 to 3 n-butyl groups in the molecule, are preferred. By highly methylolated melamines there are here to be understood those with an average of at least 5, appropriately about 5.5, methylol groups.

In the case where the component (e) is conjointly used for the manufacture of the reaction products, these diols are preferably aliphatic diols with 2 to 6 carbon atoms, of which the carbon chains are optionally interrupted by oxygen atoms. Alkylenediols with 2 to 6 carbon atoms or diethylene glycol or triethylene glycol are here of particular interest. Amongst the alkylenediols with 2 to 6 carbon atoms which are particularly advantageously used, ethylene glycol, 1,4-butanediol or above all 1,6-hexanediol may, for example, be mentioned.

The optional, polyfunctional, preferably difunctional, component (f) preferably contains, as functional groups or atoms, alkyl-bonded halogen atoms, vinyl or carboxylic acid ester groups, or at most one epoxide, carboxylic acid or hydroxyl group together with another functional group or another atom of the indicated type. In particular, these compounds are difunctional organic compounds which contain, as functional groups or atoms, alkyl-bonded chlorine or bromine atoms, vinyl or carboxylic acid alkyl ester groups or at most one epoxide or carboxylic acid group together with another functional group or another atom of the indicated type.

Particularly suitable difunctional organic compounds are aliphatic. These are, for example, epihalogenohygrins, such as epibromohydrin or above all epichlorohy- Other possible difunctional compounds are, for example, glycerine-dichlorohydrin, acrylic acid, methylolacrylamide and acrylonitrile.

The component (g) is appropriately an aliphatic tertiary monoamine, ammonia or an amine containing at least two amino groups and exclusively basic nitrogen atoms, wherein the amino groups possess at least one nitrogenbonded hydrogen atom.

Preferred tertiary amines are trialkylamines with 3 to 12 carbon atoms, for example triethylamine, tri-n-propylamine or tri-n-butylamine.

The diamines to be used as component (g) can be aliphatic or cycloaliphatic and preferably possess at least one primary amino group and a second amino group, wherein at least one hydrogen atom is bonded to nitrogen. Furthermore, just ammonia can also be used as component (g). However, di-primary aliphatic or cycloaliphatic amines are preferentially used as the component S uitable aliphatic amines are here above all polyamlnes, such as diethylenetriamine, triethylenetetramine or tetraethylenepentamine, that is to say amines of the formula (4) H N-(CH CH --NH),,CH CH NH wherein n is l, 2 or 3.

In the case of amine mixtures, a non-integral average value can also be assumed, for example between 1 and 2.

Suitable cycloaliphatic amines are above all (ii-primary, cycloaliphatic diamines, which apart from the two amine nitrogen atoms only contain carbon and hydrogen, and which possess a saturated S-membered to 6-membered carbocyclic ring, a H N- group bonded to a ring carbon atom and a H NCH group bonded to another ring carbon atom.

As examples of such amines, 3,5,5-trimethyl-1-amino- 3-aminomethyl-cyclohexane or 1-amino-2-amino-methylcyclopentane may be mentioned.

The manufacture of the reaction products can be carried out according to methods which are in themselves known, wherein the components can be reacted with one another in varying sequence. Appropriately, components (a) and (b), or (a), (b) and (c) are first reacted with one another. The reaction er the c p n with the already reacted components (a) and (b) can also take place simultaneously with component (e). The reaction with the components (d) and/ or (f) is as a rule only carried out at the end, that is to say before the reaction with the component (g).

Firstly, it is thus possible initially to react the components (a), (b) and (c) and optionally (0'), simultaneously with one another, and subsequently optionally to react the product with the components (d), (e) and (f). In this process variant the components (a), (b) and (c) are appriately reacted with one another at temperatures of to 120 C., preferably C., and the proportions are advantageously so chosen that for an epoxide group equivalent of 1, the equivalent ratio'of hydrogen bonded to amine nitrogen to carboxylic acid groups is 0.1:1 to 120.55.

Secondly, it is also possible first to react only the components (a) and (b) with one another, and subsequently to react the products with the component (c) and, optionally, in a third stage with the components (d), (e) or (f). The manufacture of the reaction products from (a) and (b) is, according to this 2nd variant, also appropriately carried out at temperatures of 80 to 120 C., preferably at about 100 C. The reaction in the second stage, with the component (c), appropriately takes place at 80 to C., preferably at about 100 C., and the proportions are advantageously so chosen that for an epoxide group equivalent of 1, the equivalent ratio of hydrogen bonded to amine nitrogen to carboxylic acid groups is 0.1:1 to 1:055.

The ratio of epoxide (a) to fatty amine (b) and acid (c) or anhydride (c) is so chosen, according to the invention, that a less than equivalent amount of epoxide is used, so that there is fewer than one epoxide group per sum of the amino and acid groups. The reaction products thus contain carboxyl end groups.

Where, in the text which follows, amino group equivalents are mentioned, what is referred to is always the number of hydrogen atoms bonded to amine nitrogen atom per molecule.

The reaction product containing carboxylic acid groups as a rule has an acid number of 20 to 80, preferably 35 to 60.

The reaction with the component (d) is as a rule carried out at temperatures of 60 to 105 C., preferably about 100 C. In most cases, this reaction takes place in the presence of small amounts of organic solvent, such as, for example, n-butanol.

The reaction with the component (e) takes place, as already mentioned, simultaneously with that of component (c).

The reaction with the component (f) takes place before the treatment with component (g) at temperatures of about 60 to C.

The treatment with the component (g) can take place at room temperature or elevated temperature, so that either merely a neutralisation, with salt formation, occurs, or, provided tertiary amines are not used, a true reaction takes place. In both cases, however, polyaddition products which are soluble or dispersible in water are produced in that provision is made, not later than on completion of the reaction, if necessary by adding a base, that a sample of the reaction mixture diluted with water shall have a pH value of 7.5 to 12, preferably of 8 to 10. For this purpose inorganic or organic bases, advantageously easily volatile bases such as ammonia, are for example used. Furthermore it is advantageous to use temperatures of at most 80 C., for example 60 to 70 C., in a reaction with (g). When using ammonia or a tertiary amine as the component (g), the reaction is appropriately carried out at room temperature. The solutions or dispersions thus obtained, treated with a base if appropriate, and preferably adjusted by means of an organic solvent or by means of water to a content of 10 to 40% of reaction product, are distinguished by high stability.

Possible organic solvents in the presence of which the reaction products are manufactured are, above all, watersoluble organic solvents, and in particular advantgeously those which are miscible with water to an unlimited extent. Dioxane, isopropanol, ethanol and methanol, ethylene glycol n-butyl ether (=n-butylglycol) and diethylene glycol monobutyl ether may be mentioned as examples.

At the same time it is, however, also possible to carry out the reaction in the presence of water-insoluble organic solvents, for example in hydrocarbons, such as petroleum ether, benzene toluene and xylene, or in halogenated hydrocarbons, such as methylene chloride, methylene bro mide, chloroform, carbon tetrachloride, ethylene chloride, ethylene bromide, s-tetrachloroethane and above all trichloroethylene.

Reaction products of particular interest are obtained if a reaction product, containing carboxylic acid groups, of at least (a) one epoxide which per molecule contains at least two epoxide groups (b) one higher molecular fatty amine, (0) one aliphatic, saturated dicarboxylic acid with at least 7 carbon atoms, and optionally (d) an aminoplast pre-condensate containing alkyl-ether groups, the proportion of the component (d), relative to all components in the reaction product, being at most 50 percent by weight, is reacted with (s) an amine containing at least two amino groups and exclusively basic nitrogen atoms, wherein the amino groups possess at least one nitrogen-bonded hydrogen atom each, or ammonia, in the presence of an organic solvent, the equivalent ratio of acid groups to hydrogen bonded to amine nitrogen, or to ammonia, being 1:1 to 1:10, and provision being made, not later than on completion of the reaction, if appropriate by adding a base, that a sample of the reaction mixture, after dilution with water, shall have a pH value of 7.5 to 12.

[Particularly advantageous products of this nature are also obtained with the abovementioned preferred components (a) to (d) and diamines.

The reaction products can be used for various purposes, above all for finishing textiles. In particular, they are suitable for rendering wool non-felting, in which case the wool is impregnanted with an aqueous liquor to which the preparation and, if desired, also small amounts of further additives, such as wetting agents or dispersing agents, have been added, and is then dried and subjected to a treatment at elevated temperature. The process for dyeing Wool and rendering it non-felting, in which, successively and in optional sequence, using the exhaustion method, the wool is on the one hand dyed and on the other hand treated with the preparations according to the invention at a temperature in the range of 20 to 100 C. and a pH value of 7 to 2, is bound to be particularly advantageous. Dyeing and applying a non-felting finish can thereby be combined in a simple manner and carried out in the same apparatus without the wool having to be taken out of the apparatus between the two processes.

Dyeing can in this case be carried out in the customary manner, which is in itself known, using any desired dyestufi, which can be used for W001, for example acid wool dyestuifs, 1:1 or 1:2 metal complex dyestuffs, or reactive dyestuifs. Equally, the additives which are customary when dyeing wool can be used, such as sulphuric acid, acetic acid, sodium sulphate, ammonium sulphate and levelling agents, possible levelling agents being above all polyglycol compounds of higher aliphatic amines, which can optionally also be quaternised and/or esterified with polybasic acids at the hydroxyl groups.

The liquor which serves for applying a non-felting finish contains, in addition to the preparation of the polyaddition product, also the amount of acid required to adjust the acid medium, [for example sulphuric acid, hydrochloric acid, oxalic acid or, especially, acetic acid. Furthermore, however, yet other salts, such as sodium sulphite or sodium thiosulphate, can be used. The liquors can, however, also contain yet other customary additives,

centages by weight.

such as agents for imparting a soft handle or bleaching agents, for example hydrogen peroxide.

The amount of the reaction product according to the invention (not counting solvent and water), relative to the weight of the wool, is appropriately 0.5 to 5%, preferably 1.2 to 4%. As has been mentioned, the process is carried out at temperatures of 20 to 100 (2., preferably 35 to 100 C., and in most cases between 5 and 60 minutes are then required for an extensive to practically complete fixing of the polyaddition product.

The sequence of the two processes is optional but in general it tends to be advantageous to dye first and then to impart a non-felting finish.

The combined process for dyeing wool and rendering it non-felting is particularly suitable for so-called machine dyeing, where the goods being dyed are static and the liquor is agitated.

If desired, the permanence of the non-felting finishes can be improved if the wool is pre-treated with a dilute aqueous solution of dichloroisocyanuric acid or its alkali metal salt prior to the treatment with a preparation which contains a reaction product.

When using treatment baths with a high content of organic, above all water-insoluble solvents, or even anhydrous baths containing only organic solvents, the process is advantageously carried out in closed equipment, for example such equipment as is used in dry cleaning.

The preparations can furthermore be employed as sizing agents for paper.

Further, dyestuifs, especially reactive dyestuffs, are well fixed to textiles, especially Wool, with the aid of preparations which contain the present reaction products, and this manifests itself, inter alia, in an improved fastness to perspiration.

Additionally, finishes using the present reaction products also improve the mechanical properties, for example tear strength, elongation at break, abrasion resistance and tendency to pilling, of the treated textile material.

Furthermore it is sometimes also possible to use the reaction products in an organic solvent, that is to say either as a solution or as a dispersion in an organic solvent. Possible solvents are here the same as those described for the manufacturing process.

Where the reaction products are insoluble in waterinsoluble organic solvents, they can be dispersed in waterinsoluble solvents in the presence of an organo-soluble surface-active agent. For this purpose the reaction product, the solvent and the surface-active agent can be mixed whilst stirring, or, preferably, the reaction product can be worked into a paste with the surface-active agent and then introduced into the solvent, whilst stirring. A stable dispersion is obtained.

The application of these dispersions is carried out in the same way as described for the aqueous preparations.
